TO ALL WHOM IT MAY CONCERN: i

Ile it known that I, J. MOORE HENDRIGKS, ot' Philadelphia, Pennsylvania, have yinvented certain new and useful Improvements iu Machines for Hulling and Dressing Rice.; and I do hereby declare thatthe following is a full and enact description of the same, reference being hadrto 'the annexed drawings, forming -part hereof, and to the letters of reference marked thereon, in which drawings-,-

Figure l is a vertical section of the machine.

Figure 2, a longitudinal vertical section of the chatting and polishing-cylinders o and u, iig. 1.

IVIy. invention relates te machines for hulling and dressing rice,'-and consists, Jdrst, of certain arms, which project radially from the movable stone of tlie'hulling-mill, in combination with an' annular surrounding chamher, the inner surface of the circuuiscribi'ng wall of which is lined with fine-wire cloth,`said chamber being provided with an aperture, located near the top of said wall, fcrthe gradual escape of the hulled rice; second, of a cylinder for chaiing the cuticle oil' of the grains of rice, said cylinder being lined with fine-wire cloth, and

' having a longitudinal shaft, which is provided with corrugated-curved arms, projecting from said shaft on opposite sides, so as to break spaces; third, of the combination of a mortar-and pestle with said chating-cylinder, anda brushing-cylinder, hereinafter described. e

To enable others shilled in the art to make and use my invention, I will proceed to describe its construction and mode of operation. i

In fig. l, A represents the frame of the machine. a represents the hopper, b the stationary stone, and c the movable stone of the hulling-niill. cl, a cylinder, which surrounds the stones be, and encloses an annular chamber, e.4 f is a shaft, working in astep at its lower end, carrying a pulley, g, for the belt by which it is turned. The upper end of said shaft passes through. thestationary stone and is fastened to the movable stone c by means of a cross-head,`/l. All these parts are in the usual form. I provide the movable stone e with one or more arms, z', and I line the inner surface of cylinder rZwith ne-wire cloth, and I make an aperture, j, through the cylinder d, near its top, for the gradual escape of the mixed rice and hulls.v his a mortar; Z, a pestle, with a projection, Z; ma shaft, with projections m. This shaft has 'bearings' in the frame of the machine, and lcarries at ont) end a pulley (not shown in the drawings) for the belt,.by which itl is connected with .a driving-shaft. n is au aperture, leading from the bottom-'of .themortar 7c into the top ofthe chang-cylinder o. This cylinder o consistsot` a wooden framework, with solid ends, thel inside face ofsaid frame being covered with fine-wire cloth. j) isa shaft, which has bearings in each end of said'frame. 'The' shaftp is provided with two or more curved corrugated arms, q, arranged so as to break spaces, and thus more'completely ehafe the rice. .The aperture it is closed with u'slidc, 'which corresponds with it in form. 'ej is an aperture; leading from the bottoni of the cheating-cylinder o, into a receiving-chamber,s, iig. 2; t is another aperture, leading from chaumbers to the tapered cylinder u.

Theaperture t is closed with a slide, u, g. 2.' The cylinder et is composed of a wooden framework, withvsolid ends,rthe inner face of the frame being covered with ine-wire cloth1 zu is a shaft, with bearings in the ends of cylinder u. Shaft fw carries a tapered drum, m, covered with sheepskin, with the wool on, and iswrapped with a textile rope spirally, as shown in fig. 2. ,fl/.is e. pulley for a belt, by which shaft "w is connected with a driving-shaft. e, iig. 2, is an aperture, by which the rice escapes from cylinder fw.

The rice which is intended to be treated is'placed in the hopper a, and thence drops down through the eye ot' the movable vstone c, passes between the two stones, and is thrown out into the annular surrounding chamber e,jland is worked around and upward in mass by the arms z', the grains rubbing against'each other, and against the rough -surfaces of the chamber and m'ovingrstone. As soon as the rice works upy as high as the bottom of aperture j, it begins to discharge throughvrsaid aperture. This operation removes the hull from thevrice, and

loosens the euticle, preparatory to the further operations, which; will now describe. The rice is next put into the mortar 7c, where it is pounded by the automatic pestle, '2. The slide is withdrawn from the aperture 11 und the. rice runs down into cylinder o, where it receives additional attrition, the revolving arms q working through it,- and rubbing it against the wire lining, throwing oit` the cuticle through .the m'eshcs of the wire cloth. After ih e cuticle has been entirely removed from the rice by the operations last described, the slide vis withdrawn, and the rice runs down into the chamber s, and thence, through the aperture t, is fed into the smaller end ofthe tapered cylinder u; Here it is polished by means of the revolving covered drum '512, and escapes throughthe aperture 2,fig. 2, in a thoroughly-cleaned condition.

The cylinder eZ might be made of stone, and then the lining of its inner. surface with wire cloth could be The mortar and pestle are constructed of the materials usually employed in the making of dispensed with. such articles for tbe purpose herein described.

Having thus described my invention, I claim, and desire to secure by Letters Patent- 1. The cylinder o, in combination with its shaft and corrugated curved 'arms g, for cbang the cuticle, and removingthe same from the rice, substantially as set forth. v

2. The combination of thel mortar and pestle c Z, the'cylindcr o, (with its snatt, p, and corrugated arms gb) and .the4 polishing-cylinder u, with its cov-ered drum, all constructed and arranged in thc manner and for thc purpose substantially as set forth.
